FreeBSD: jail can not set security.jail.sysvipc_allowed [closed]

Solution found. The following does work for me. On the host, do:

root@host# jls   JID  IP Address      Hostname                      Path     3  -               some.jail                     /usr/jails/somejail

Find the correct JID, 3 in my example. Then, on the host, issue:

jail -m jid=3 allow.sysvipc=1

postgresql freebsd jail

There are some new features for jail in special granularity, we need allow change sysvipc_allowed for each jail put this in /etc/rc.conf:

jail_example_parameters="allow.sysvipc=1"

postgresql freebsd jail

I found the problem after my teammate's help.

Because I use /etc/jail.conf, I have to add a line "allow.sysvipc" to enable system share memory.

in host machine,

  /etc/sysctl.conf  security.jail.sysvipc_allowed=1  /etc/rc.conf   jail_sysvipc_allow="YES" (DO NOT have to do this, remove it)
